Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 Purpose This invention improves the safeness of the riding experience especially in heavy traffic conditions where unexpected circumstances can require a sudden stop of the bicycle. It is best suited for road push-bikes and for mountain bikes. The purpose of this invention is to prevent the front wheel of a bicycle from locking when sudden pressure is applied to the brake hand lever of the front wheel brake by the rider. Preventing the locking of the front wheel, will help the rider avoid loss of control and reduce the risk of falling and resulting injuries. Summary This system regulates the braking of the front wheel based on the amount of pressure exercised on the saddle and on the brake hand lever. Pressure on the saddle is exercised by the mass of the rider's body. To detect such pressure, the modified saddle has a mechanism that, when the rider is seated on it, actuates a lever that regulates the tension of the cable of a modified Front Wheel Brake by pulling it part of the way. The braking system can be fully engaged when the rider also presses the Brake Hand Lever with his hand while seated on the saddle. When there is a sudden deceleration due to a hard braking of the bicycle, the momentum of the rider's body mass which is bigger than that of the bicycle, tends to separate the rider from the saddle frontwards and upwards. It is at this moment when there is less pressure over the saddle that the mechanism releases some of the tension on the brake cable thus releasing also pressure off the Brake Arms of the front wheel preventing the Brake from locking the wheel. When that happens, as the Brake Arms release some pressure off the Brake Pads over the Wheel Rim, the bicycle reduces the deceleration, the mass of the body of the rider goes back on the saddle increasing the tension 11 ag Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 on the front wheel brake cable and thus having a progressive braking of the bicycle. My invention differs from previous inventions, like US 605735 A (MAYER) 14 Jun 1898, DE 004421591 Al (MOZER) 04 Jan 1996, DE 002845295 Al (RUDOLPH) 30 Apr 1980, US 6333266 A (JAMIESON) 19 Sep 2899, 15Apr 1986, all of them inventions that a meant to offer a system to brake the rear wheel of the bicycle without using the hands, invention US 4582178 A (HUNEAULT) claiming to brake both wheels at the same time tilting the saddle but not offering any type of regulation preventing the front wheel from locking and invention WO 2012/009683 Al (SHAPIRO) 19 Jan 2012 which again is a system that intends to brake only the rear wheel, and even though the system is situated near the saddle and claims to be able to offer some type of regulation over the braking of the rear wheel, it does not use the saddle itself to brake or provide a regulation of the brake action and does not claim to offer an anti-locking action on the front wheel when a sudden stop due to hand actuated braking occurs. Unlike the aforementioned inventions, my invention intends to control the tension on the cable actuating the arms of the front brake to control the braking of the front wheel and ultimately to avoid a sudden lock of the wheel. Most of the previously mentioned inventions require the rider to move his/her buttock forward or backward to actuate the mechanism in the saddle or near the saddle. That requires a retraining of the habits of the rider and I do not believe are the safest ways of braking a bicycle. In contrast with that, my innovative system does not affect the way in which riders are used to ride their bicycles, nor does it require retraining the way in which they normally ride and brake the bicycle. The rider just needs to seat as usual and let the mechanism actuate by itself. Applications This system can be applied on any type of bicycle that uses Linear-pull brakes or direct-pull brakes, commonly referred by Shimano's trademark as V-brakes and also on Single-pivot side-pull calliper brakes in their front wheel. 21P g Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 Ideally, this system would use modified brake arms where both arms provide the cable housing detent (see figures 17 and 19 for this ideal configuration of the front brakes for Single-pivot side-pull calliper brakes and for Linear-pull brakes). Alternately, if the system has to be mounted using existing brake arms, a small Adaptive Screw can be fitted on the Brake Arm where the Cable Clamp normally is, providing a Housing Detent for the Cable Housing and a hole where the cable going to the mechanism in the saddle can run free (see figures 18 and 20 for this alternative configuration). In my prototype I added a spring for added strength to pull the saddle lever although that is not necessary as the springs provided in the brakes are usually strong enough. The system can be applied following the same principles on mechanical (cable-actuated) disk brakes. It can also be applied on hydraulic actuated disk brakes provided the disc brakes have their pads actuated from both sides of the calliper (double cylinder). In that instance, similar to the hand lever which actuates a piston in a cylinder lined to one of the cylinders on one side of the calliper, the lever under the saddle would also actuate a piston in a hydraulic cylinder lined to the other cylinder on the brake calliper. Detailed Description of the Invention As explained in the Summary, the novelty of this invention does not rest on the different components or parts that make this New System, as they are common to many mechanical applications. The Inventive Step has to do with their adapted design, modified use and interaction, making them work in a unique way allowing this New Braking System to, unlike many other brake systems, control the front wheel braking of most bicycles with cable actuated brakes. This section is intended to accurately describe all the different components or parts that make up this invention and to show how they work and interact to provide a regulated braking of the front wheel of a bicycle and to ultimately prevent the front wheel from locking when there occurs a hard braking. 31 a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 The illustrated mechanism to actuate this ANTI-LOCKING BRAKE SYSTEM FOR FRONT WHEEL OF BICYCLES (from now on called "System") includes, apart from a complete bicycle, using Single-pivot side-pull calliper brakes or Linear pull brakes on the front wheel and a Brake Hand Lever clamped in the handle bar of the bicycle with its Cable Housing Detent and Adjusting Barrel and Locking Nut that comes as part of Brake Hand Levers, the following itemized parts: 1. A Swinging Saddle Shell (figure 1 item a) whose modifications or adaptations include: 1.1. a Hinge Barrel (figure 1 item b) to provide a pivoting point under its nose (figure 6 item o and figure 8 item a) when linked to the Hinge Clevis (figure 1 item j) provided at the front of the Saddle Rails (figure 1 item o) statically clamped with a Bracket at the top of the Seat Post (figure 1 item f and figure 6 item p) of the Bicycle so that the Saddle Shell (figure 1 item a) can swivel up and down from said pivoting point, this movement being limited in its way up by an L shape Lever acting as a link (will be discussed later) and in its movement down by the Saddle Rails Bridge Bar 1.2. this Modified Saddle Shell also incorporates a Clevis facing down toward the rear (figure 1 item c) to attach one extremity of the L shape Lever (figure 1 item d) that has a slotted hole (figure 7 item e) by means of a Pin (figure 1 item m) or a small screw and nut as in my prototype (figure 9 item a). This Lever has to be able to move and swing freely all through its slot race, thus allowing for the saddle to swing vertically 2. The Saddle Rails incorporating the following: 2.1. a Hinge Clevis (figure 1 item j) in its front where a Pin (figure 1 item k) can be inserted to attach and pivotally link the Hinge Barrel under the nose of the Saddle Shell allowing the Saddle Shell to swing up and down as mentioned in description Item 1.1 4| a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 2.2. this Saddle Rails are held together from their rear by a Bridge Bar (figure 1 item h) so that they form a sort of a fork shaped frame (figure 1 item o) 2.3. The Saddle Rails also incorporate a Rear Clevis on the back (figure 1 item i) protruding horizontally to the front of the bicycle from the Bridge Bar to provide the fulcrum of the L Shape Lever (figure 1 item d) by means of a Pin (figure 1 item I) or a small screw and nut, as in the case of my prototype (figure 9 item b), inserted through the holes in the Clevis and the hole in the L shape Lever so that the Lever can pivot freely from its fulcrum 3. The aforementioned L shape Lever (figure 1 item d and figure 7) that has two connected arms of the same length forming a 90 degree angle where the fulcrum is at the vertex, wherein one arm (Arm 1) is pointing to the front of the bicycle from the fulcrum and in line with the horizontal plane of the bicycle and the second arm (Arm 2) is perpendicular to the horizontal plane of the bicycle and pointing down from the fulcrum of the Lever. Arm 1 of said Lever links the Saddle Shell to the rear of the Saddle Rails and limits the extent of the swinging of the Saddle Shell. Arm 2 transforms the substantially vertical swinging movement of Arm 1 to a substantially horizontal swinging movement at the end of Arm 2 as the L Shape lever pivots from its fulcrum and transfers this movement to the Front Brake by means of the Brake Cable clamped to a Cable Clamp Pivoting Bush located at the end of Arm 2 of the L Shape Lever in a provided Small Clevis. A detailed illustration of the Lever can be seen in figure 7. An illustration of its place in the system can be seen in figure 6 item 1. That Lever incorporates the following: 3.1. a Centre Hole (figure 7 item a), in the front end of Arm 1, through which the L Shape Lever is linked with a pin or a small screw and nut, as in the case of my prototype, to the Clevis protruding from the Saddle Rails Bridge Bar so that said pin actuates as the fulcrum (figure 1 item I) for the L shape Lever as mentioned in description item 2.3 5la Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 3.2. a Slotted Hole (figure 7 item e) in the front end of Arm 1, through which the L Shape Lever is linked with a pin or a small screw and nut (as in the case of my prototype) to the Clevis provided under the Swinging Saddle Shell and whose width (that is the width of the slotted hole) is slightly bigger than the diameter of the linking pin thus allowing said Saddle Shell to vertically swing to the extent allowed by the race length of the aforementioned slotted hole 3.3. a Small Clevis at the end of Arm 2 of the L shape Lever consisting of: 3.3.1. a hole (figure 1 item g and figure 7 item f) perpendicular to the front to rear axis of the bicycle and in line with the Bicycle's horizontal plane whose diameter is about 0.1 of a millimetre bigger than that of the Cable Clamp Pivoting Bush to allow said Bush to rotate 3.3.2. a Cable Groove (figure 7 item g), perpendicular to the previously mentioned hole axis (3.3.1) forming a small clevis with a space wide and long enough to allow the cable going through the Pivoting Bush to move freely in the Lever 4. The aforementioned Cable Clamp Pivoting Bush (figure 1 item g and figure 7 item c) which clamps the cable that transmits the tension to and from the Brake Arms. An illustration of it can be seen in figure 7 item c and an illustration of its place in the System can be seen in figure 6 item m. As shown in the illustrations this Cable Clamp Pivoting Bush has the following features: 4.1. a Cable Hole at its centre perpendicular to the longitudinal axis of the Bush where the Brake Cable is inserted (figure 7 item d) 4.2. a Threaded Hole (figure 7 item b) in one side of the Bush (no preference in choice of side), longitudinal to the axis of the Bush through to the Cable Hole 4.3.a Grub Screw to be screwed into the Threaded Hole to clamp the Brake Cable in position once the tension is adjusted 61 a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 5. A Cable Housing Detent near the top of the Seat Post that holds the Saddle Rails aligned as much as possible with the Cable Clamp Pivoting Bush fitted in the L shape Lever to stop the Cable Housing but allowing the Brake Cable to go through to the Cable Clamp Pivoting Bush. This Detent can be provided externally attached to the Saddle Rails or as part of the Bracket that attaches the saddle to the Seat Post. In the case of my prototype, I provided this Cable Housing Detent as part of the Bracket and through the Seat Post with: 5.1.a two dimensional all through hole (figure 2 items c and d) at the top on the tube that forms the Seat Post, longitudinal to the bicycle's front to rear axis and in line with the horizontal plane of the bicycle, drilled through the Bracket holding the Saddle Rails and the tube of the Seat Post. This two dimensional hole comprising the following: 5.1.1. on the side facing the front of the bicycle; a hole, drilled through the Bracket and the front side of the tube of the Seat Post, a bit over 5mm in diameter to allow for the Cable Housing or sleeve (figure 2 item a and figure 6 item h) to be inserted. In this side, a Cable Ferrule (a sort of a cup with a small hole in one side and a small flange on the other) can be inserted to protect the Cable Housing. The perforated Bracket and the Cable Housing going into it can be seen in figure 10 item b 5.1.2. on the opposite side of the Seat Post tube, facing the rear of the bicycle and towards the L shape Lever; a smaller hole is drilled so that the Cable Housing cannot go through but big enough to allow the Brake Cable to run free 6. The System includes an Extra Cable Housing Detent, preferably provided as a set of Modified Front Wheel Brake Arms of Single-pivot side-pull calliper brakes or Linear-pull brakes, wherein said modification consists on the fact that the Arm that otherwise would have the cable clamp is manufactured with a Cable Housing Detent mirroring the Cable Housing Detent of the other Arm so that both side arms of the Front Wheel Brake will have housing detents to accommodate the cable housings, one coming 71 a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 from the Brake Hand Lever and the other from the L Shape Lever (illustrated in figure 6 item e and in figures 17 and 19). 7. Since at the moment commercially fitted brakes do not offer the possibility described in Item 6 of this description, the aforementioned Extra Cable Housing Detent (Item 6) can be provided in existing Front Wheel Brake Arms of the aforementioned brake types by an Adaptive Screw mounted where the Cable Clamp would normally be fitted. An illustration of this Adaptive Screw is provided in figure 5. Figure 13 shows this Adaptive Screw fitted on the right lever of the v-brake of my prototype System and figures 18 and 20 show the configuration of the two different front brakes types using the Adaptive Screw. This Adaptive Screw comprises the following: 7.1.a threaded screw and its nut (figure 5 item b, Metric 6 in the case of my prototype but that dimension can vary according to the hole in the lever) to attach this Adaptive Screw to the hole provided for the Cable Clamp in the Brake Lever a head, in the shape of a cylinder, longitudinal to the axis of the screw, of about 10 mm in diameter and about 10 mm in length, where a two dimensional through hole is drilled in the middle of such head perpendicular to the screw's longitudinal axis; where half of the hole (figure 5 item c) is big enough to allocate the Cable Housing and the other half (figure 5 item d) is smaller allowing only the Brake Cable to go through while stopping Cable Housing 8. The System further comprises a Single Brake Cable going all the way from its location in the Brake Hand Lever to the Cable Clamp Pivoting Bush inserted in the Small Clevis provided at the end of Arm 2 of the L shape Lever. The Cable incorporates: 8.1. the usual Cable Housing expanding from the Brake Barrel Adjuster in the Brake Hand Lever to the usual Cable Housing Detent provided in the Brake Arm 81 a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 8.2. An added Cable Housing from the Extra Cable Housing Detent of the Brake Arms to the Cable Housing Detent provided at the top of the Seat Post on or near the Bracket that holds the saddle 8.3. The path of the Brake Cable is as follows: The Brake Cable goes from its location in the Brake Hand Lever, going inside the Cable Housing from the Brake Barrel Adjuster of the Hand Brake Lever to the Housing Detent on the Brake Arm with the original Cable Housing Detent, it further goes through the Brake Arms themselves, later through the inside of the Cable Housing going from the Extra Cable Housing Detent in the Modified Brake Arm to the Cable Housing Detent at the top of the Seat Post and coming out from that Housing Detent to be clamped inside the Cable Clamp Pivoting Bush inserted in the Small Clevis located in the L Shape Lever 8.4. The tension of the Brake Cable can be adjusted by pulling the cable until some tension is felt on the Brake Arms and the cable pulls the L shape Lever lifting the saddle, then the grub screw in the Cable Clamp Pivoting Bush can be tighten to clamp the Brake Cable. Next, without touching the Brake Hand Lever, pressing down the Saddle Shell until it rests on the Saddle Rails Bridge, in that condition, the Brake Pads should be about 1mm from the wheel rim. When the saddle is released, the springs in the Brake Arms will further open the arms and pull the cable attached to the L shape Lever by means of the Cable Clamp Pivoting Bush slightly rising the Saddle Shell (this instance is pictured in figures 4 and 8). A fine tuning of the tension of the cable can be achieved using the Brake BarrelAdjuster (figure 15 item c) that exist in all commercially provided Brake Hand Levers 9. As mentioned previously, in order to link all the Hinges in the System (figure 1 items k, I, and m), it is preferred to fit commercially provided Pins. These Pins have a flange in one side and a Quick Lock Washer on the other side to prevent the Pin from getting out. However, in the case of my prototype I used M4 screws and nuts with a nylon insert lock in place of the pins. 91 a Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 To be able to test my System I produced a prototype as follows: * Fabricated the new Saddle Rails out of 7mm diameter steel bar, welded the Bridge Bar on its rear part. Also fabricated and welded on it the Rear Clevis and flattened the two front rails and drill on them a hole to serve as the front Hinge Clevis for the Hinge Barrel of the Saddle Shell * Fabricated a modified steel Saddle Shell with its Hinge Barrel and Rear Clevis to be attached using small screws to the original plastic Saddle Shell of my old saddle * Machined in the milling machine the L shape Lever out of brass material * Machined in the lathe the Cable Clamp Pivoting Bush out of steel and got an M3 grab screw * Machined in the lathe the Adaptive Screw out of 10 mm round steel bar and drilled on it the two dimensional hole to serve as a Housing Detent * Purchased a few meters of Brake Cable and its Housing, screws and nuts * Drilled a Two dimensional all through hole, toward the top of the Seat Post and also a through hole on the Bracket that attaches the Saddle Rails to the Seat Post to use as Cable Housing Detent * Finally I fitted all the parts together and provided Metric 4 Allen socket head and Metric 4 Hexagonal nuts with Nylon Insert as pivoting Pins In case of mass production of this System, the manufacturing process of the essential parts could be as follows: * Saddle Rails: It can be shaped stamping a round bar on a press using a specifically designed die. The Holes of the Front Clevis can also be stamped and the Rear Clevis can be also press stamped and welded on the Rear Bridge of the Saddle Rails * Saddle Shell: It can be made out of plastic polymer by injection moulding providing the Barrel and the Clevis Hinges for the L shape Lever. The Saddle Cover will be attached to the Saddle Shell as per normal procedure 101>: n Anti-locking Brake System for Front Wheel of Bicycles By Francisco Javier Gonzalez. February 13 2014 * L shape Lever: This part can be produced out of Brass on a CNC machining centre, can also be produced of some resistant polymer or metal alloy by injection moulding or even press stamped e Cable Clamp Pivoting Bush: I am sure this item can be commercially obtained but if not, this part can be fast produced on a fast production automatic lathe * Cable Housing Detent in the Seat Post: This can be easily produced during the manufacturing process of the Saddle components by drilling the proper holes on the Seat Post and on the Bracket if needed. Another type of Cable Housing Detent can be also provided externally attached to the saddle rails or on or in the Bracket (depending on the type of Bracket) that holds the Saddle Rails to the Seat Post, that may require changing the position of the Hinges that hold the L shape Lever to one side. However that would not change the way the System works * Modified Brake Arms: This should be provided by the brakes manufacturers, as they only should provide the Cable Housing Detent in both arms instead of just one as usual e Adaptive Screw: To modify existing brake systems, this part should be provided. It can also be manufactured on a fast production automatic lathe These suggested manufacturing processes for the different parts of the System are by no means the only ones that can be used and if the time comes to produce the parts a thorough study of the best processes and materials should be carried out in order to maximise quality and productivity and reduce costs as possible Brief description of the illustrations and pictures Following I have provided several schematic drawings picturing the basic concept of using the saddle as part of my innovative brake system.
